Abstract
The differences in morphological and physiological characters of three wheat varieties to low phosphorus stress were studied using solution culture.The results were presented as the follow:(1)Comparing with the control group,the spring wheat seedlings unders low phosphorus stress were low in height and short in root length;and numbers of roots,the activity of SOD and POD of the roots,total root length,total absorbing area,root dry weight,active absorbing area and root activity decreased dramatically,but the stress obviously increased the root /shoot ratio and Lateral root numbers;the change tendencies of different genotypes were similar,but the range of changes was different remarkably;(2)The morphological and physiological characters were significantly different among 3 wheat genotypes,as the concentration of P decreased,the variations of corresponding parameters increased;(3)The morphological and physiological characters of roots could be reference to screen P efficient uptake in wheat,and Jiachun 1 was most tolerant to the low concentration of P in the genotypes.
